This example describes how the administrator manages the routing with the BGP
attribute. All routers are configured with BGP. OSPF is used by IGP in AS200.
Router A is in AS100, functioning as the BGP peer of Router B and Router C in
AS200. When Router B and Router C run IBGP to Router D, Router D is also in
AS200.
